Specification of Letters Patent.

Application filed July 2, 1933. Serial No.

Potent-ed May in, mild To (ZZZ whom it may comic/")2 it known that I, li iiimni 'l. Trio-remson, a citizen of the United bteies, residing at South Bend, in the county of St. Joseph and State of Illillllllfl,'llfl'\'% invented a new and useful improvement in Traction-Em gines, of which the following is o specificstion.

My invention relates to a new kind of steerable drive wheels, whereby the drive- Wheels are easily and ellicicntiy steered to o grist degree of angle, thus permitting the turning of large tractors in comp:irutivcly small placesv The wheel being pivoted on a direct line-of the center of the symmetric plane of the trend causes very little resistance in steering or changing the angle of I have also provided means for sliding oppositely disposed hovel gears onthe vertical pivot'sliaft for chzingin them forward I to reverse speed, or vice verso. For the henrings of the said pivot shaft l have provided means for use of boll-hearings which are in action Whenever said Wheels are in motion The main wheel bearings are run on rollers incased and dust-proof. The axle is also provided with roller-bearings properly protected fromi dirt. Placed oppositely and close to main costings for frame are two oppositely disposed bevelv gears keyed to axle-filer engagement with o sen1i-circle gear pivotslly fastened to inside wheel bearing for the purpose of steering the Wheels from motion of axle. By having oppositely disposed gears the direction. of the Wheels can be changed either to right or left by engaging the semi-circle gears with either one of seid gears occording to the direction desired. hen the controlling lever is released, :2. spring disengeges said semicircle gear. ll'lenns are also, provided so that only one gun maybe engaged at n time. Means are also provided to disengage hand steering Worm when either of said semi-circle gears are engaged I aim to provide a tractor drive wheel pivoted in the center of the trend with simple, dlll lb1e;fi|11d ellicientconstructionnnd design.

With the above recited objects in View, and others of a, similur nature, the invention consists in the construction. combination,

, and arrangement of ports hereinafter set i orth'in and falling within the scope of theoppended claims.

it vertical, longitudinal, sechalf, taken on a center line; showing bevel gears with one meshed for forward speed. Fig. 2, is e sectional ,end view of the whole wheel at A. A. in Fig. 1 Fig. is ll sectional bottom view of the whole Wheel at B. 13., taken from the bottom instead of from the top, to show the semicircle steering gear.

Siniilo reierence characters designate like parts throughout the several views.

Referring now to the accompanying drawings in detail, the letter B indicates the d ive axle, and the letter C indicates the axle hearing the engine frame support, while D indicates the Wheel. inside hearing 2, is pivoted on the vertical pivot shaft 3 and lull-hearings -l support casing and also form bearing for vertical pivot shaft 3. llollcrs 5. is; main bearing for drive Wheels,

lF-igure 1, is tionol view in and 6 together with n portion of F, fitted with imll-benrings is means for holding wheel in proper place and olineinent. Keyed on. the ends of the drive axle, B, are bevel. gears '1 which mesh with either of the bevel o'cors S) and 10, and gears 9 and 10 mesh with hovel gear 8, which is secured to outside b65113".

- lion broadly, but

I claim: 1. The combination, in u traction engine,

of a driving: gear, tvvo oppositely placed gears and solidi connected with each other loosely mounted on a vertical pivotshaft, adopted to be shifted, engaging either one or neither and transmitting; the power by another bevel gear to the drive 'wheel.

2. A driving gear engaging either of a pair of oppositely placed gears pivoted on comer in direct line of two directly opposite points of the center of the Wheel trend.
